Fish farming has many commercial losses due to diseases. Parasitic diseases account for a large portion of this losses. In Brazil there are records of various parasites causing damage, and in Goiás were not found recent data on the occurrence of parasitic infections in commercial fish farms. This study aimed to identify and establish the occurrence of ectoparasites of tambacu hybrid, raised in commercial fish farms in the microregion of Goiânia-GO. Nine fish farms were evaluated between August and December of 2010, and samples were colected in two separate visits. Fishs were examined by direct microscopy for observation of the parasites. Of the 90 tambacu fish examined 46 (51.11%) were parasitized. It is concluded that hybrid tambacu fishes raised in the Microregion of Goiânia has the following parasites: Monognea sub-class, Trichodina sp.. Piscinoodinium pillulare, copepodids of Lernaea sp. and Dolops sp.
